In the latest version of my notes I forgot to mention that I am using
2.0.13 from Debian unstable. It was in the first draft.

Thomas what is your locale?

If run lilypond with my default locale (LANG=it_IT.utf8) I get this
error too; as I wrote somewhere, running the "gs" command on its own
showed that in my case this was due to the EPS file containing commas
as decimal separator instead of periods.

Running lilypond like this worked around the issue for me:

  $ LANG=C lilypond-git

Does this work for you too?
BTW setting only LC_NUMERIC instead of LANG could be enough.

As happened often in my naive attempt to move things forward I could
spot where the problem was but due to my lack of knowledge about
lilypond and guile I am not always able to figure out what the correct
fix is.

For instance if David, or someone else, could confirm that patch 0005
[1] actually makes sense I would propose it for inclusion in lilypond.
